' AEnorLANE FLYING TOY.

' Application filed .luly 13, 1925. c Serial No 43,094.

This invention relates to a toy, and particularly to such a toy in the form of an airship or aeroplane.

It is an object of this invention to provide a' very simple, pleasing; efficient and inexpensive toy aeroplane.V

It is a further object of the invention to provide a toy aeroplane'made fromsheetI material comprising a very small number of toy aeroplane and adapted to receive a plane' and supporting wheels. v

It is still another object of the invention to provide a novel" blank adapted lto form the supporting wheels for the aeroplane. These and other object s and advantages of the invention will be set forth in the following description made in connection with the accompanying .drawings in which like reference characters refer to the same parts throughout -the different views,l and in which, v

Fig. 7 is .a used to form the supporting wheels; and

Fig. 8 is a view of the. piece usedl to form the vertical tail rudder of the aeroplane.

Referring to the drawings a toyaeroplane is shown comprising a fusev age 10, a plane 11 secured thereto, supporting wheels l12 s ecured to the fuselage, a propeller 13 secured from said.' central portion.

developed view of the blank to the 'front ofthe fuselagefby a member 14, a vertical tail rudder 15, a rod 16 having a head member or pin 17 projecting longitudinally thereof 'at one end receiving the looped end of a string 18 which is secured at the other end and a vbow member 19 having 1ts ends "secured 4in the fuselage 10 at each side of the plane 11.

The f selage 10 is folded up from a -onepiece b ank shown in Fig. 6. This blank l comprises a central portion 10a of rectangular shape divided into a plurality of zones 10b by. lines 10c 'extending longitudinally The blank also comprises end portions 10d and 10e which are tapered outwardly or have outwardly converging side edges. The end portion 10 is divided into a plurality of zones 10 by lines 10g and it will be noted that said lines l()g converge toward their outer ends -so that Athe pones' 10 taper toward the outer endsV and 1t .will alsobe noted that the inner ends of the zones 1()t arel co-extensive with and abut the adjacent ends of the zones 10", the c inner ends of lines 10g meeting the outer' ends of the lines 10c. The end portion 10dl which also converge toward their outer ends so that zones 10h are tapered toward their outer ends. The lines 10i, at their inner ends, aline with the lines 10c so that the Y inner ends of zone 10h are (3o-extensive with and abut the adjacent ends of zones 10b.

Each of the end portions 10 and 10d has an outwardly extending pointed Y triangular notch 10j out therein at the outerlines 10g and 10i respectively. It will be seen that ,the

vcentral 4zone 10b is joined t'othe longitudif nally alined zones 10t andlOh but that the otherzone on the end portions 10"- and 10d are separated from the. adjacent zones of the centralv ort-ion 10.

lis als divided into zones 10h by lines 10i The blan is also provided with openings or slits 10k, the same being in the central and end portions and along theoutermost lines 10g, 10e and 10, respectively, at one side of the blank. The blank also has projecting tabs or tongues 10k projecting from its central and end portions at the opposite edge from which the slits 10- areadjacent, which tongues are adapted, when the blank is folded, respectively to enter-the slits 10k.

to be folded along lines indicated as 10n and 10', respectively. The end portion 10d, which is the rear portion, has a Acentrally projecting strip 10 which connects the central zone 10h with the horizontal tail rudder portion 10P,"said portionlhaving a central slit 10q formed therein, said central zone 10h also having a central longitudinale` slit 10q at its rear" end. The p\ortions'10 and 10P are adapted to fold along the lines 10. The central zone 10b has slits 10r at each side thereof onwthe lines `10 adjacent its forward end. Theouter zone 10h a'nd 10f are also provided with holes 10S adjacent their inner ends, and the central zone 10fland the members 10m are provided withl centrally disposed holes 10t. The rear portion of the outer zones 10h have recesses 10v cut therein forming'the edges 10W. i

The wheels 12 of the aeroplane are formed` from a blank having a central narrow portion 12, at each end of which is a pair of circular portions 12b arranged inv .substantially tangential relation and connected adjacent their point of tangency. The outerA circular portions 12"l have projecting there from strips or tabs 12, said tabs having narrowed inner" portions and also having formed therein-inwardly extending slots 12d. Thev circular portions 12b are adapted to fold along the dotted lines 12e therebetween and the portion 122L is adapted to be folded along the dotted lines 12f. The vertical tail rudder 15 is formed from a 'piece 15n shown in Fig. 8, having extending vertically thereinto a slot or slit 15". This slotl forms the 'tongues15c and 15d and said rudder has a right-angled recess at one side forming the edg 15e.

In assemblin the device the blank for the fuselage 10 .is folded along the lines 10c, 10g and 10 into polygonal shape, said shape being substantially square in cross section, as shown in Fig. 3. The central zone 10", 10hand 11t are at the bottom of the fuselage and the outer zones 10, 10b and 10h having thereon the tabs 10k overlap respectively the zones -10f, 10b and l()h at the other side of the blank and are at thetop of the fuselage, the tongues 10k entering the slits 10k. When the blankiis lthus folded, theinner yends of the zones 10dl and 10e at the outer side of the blank have their pointed ends or flaps 10" and 10h', as shown in Fig. 1, overlapping the adjacent zone10a at the top of the fuselage. The plane 1 1 which comprises merely a sheet of material shaped, as shown in Fig. 1, is then placed in position under the Apointed ends 10" and 10h. The holes 10", in the respective end portions 10e and 10d arenow in vertical alinement and the bow or bail member 19 has its ends inserted through these ,holes and the horizontal parallel portions at the ends of member 19em- 10aA and 10e, as well as the inserted plane 11, l as clearly shown in Fig. 2. It will also be `noted'that there is a triangular pointed portion 10f and 10h at the inner ends of zones 10? and 10h, respectively, at each side of the central zone, which portions are disposed inwardly of and overlapping the zones 10b of the central portion 10a when the fuselage is in folded condition, as clearly shown in Fig. 2. The fuselage being folded, as described, is heldin folded position by the .g tongues 10kl and the member 19 and the end portion 10m is then folded along theA lines 10 and 10', as shown in Figs. 2, 3 and 5, zone 10m being spaced some distance in- Wardly of the zone between the lines 10m.

'- The holes" 10t then come into horizontal alignement and the member 14 is inserted th'roughthe propeller 13 and lthen through the holes 10t, as shown in Fig. 5, said member 14 having a portion 14a bent at right angles and extendingdownwardly inside of the lzone 10m and having another portion 14b bent horizontally at right angles to eX- tend through the hole 10t in the central zone .10f which is at the bottom'v of the fuselage. The member- 14` has a 'circular portion formed in its outer end to prevent outward movement of the propeller 13. The member 14 thus holds the propeller 13'in position and assists in holding the, end` of the blank ofI member '10 in position. The portion 10J of the fuselage blank is now folded upwardly at ay right angle along the inner line 100 `and is then reversely folded along Ythe center line 10 and is again bent or'folded out-v 710?, as shown in Fig. 4. The vportion betweenthe inner pair of lines 100-v thus closes the rear end ofthe fuselage and the portion 10P is disposed in horizontal relation. The vertical tail rudder 1,5 is now placed in position with the portion 15c projected downwardly through the inner slit 10q and the portion 15d projects downwardly through he outer slit 10q in the horizontal 'tail ruder. between the inner and outer lines 10. ymay be here stated, that there is a slit formed in the top of the folded fuselage 12 by the recesses 10b which are cut in the rear ends of the outer zones 10h, said slit being formed betweenthe spaced edges 10w of said recesses. The4 member15c passes through this latter mentioned slit in the top of the folded fuselage andthe surface 15e fits fiat against the top surface of the horizontal rudder portion 10D outwardly of the cute slit 101.

The blank for the wheels 12 is now folded lupwardly along the lines 12e to bring the kcircular portions 12b into overlapping contacting relation. The blanlcis then folded downwardlyalong the lines v12. The pro- Theslit 15b then embraces a portion It` brace the ends of the overlapped zones 10d, jections 12c then project vertically and 180 I' extending centrally of said fuselage at the vslits r and moved forwardly so that the slits 12d embrace the -thickness of the cenv member 19, a loop formed in the other end of the string and disposed about the shank of the headed member 17 which is'then in-` serted in rod 16. The rod 16 is, in practice, from 15 to 24 inches in length.

In operating the device, the free end of the rod is held in the hand and the other end of' thev rod moved in a circular path about the head of the operator. The action of the air on the propeller 13 causes the same to rapidly revolve and 'the plane 11 and the rudders 15 and 1()p hold the plane in upright position. The flight of an actual aeroplane is thusclosely simulated. From the above description it is seen that the applicant has provided a very simple and efficient toy and one which can be quickly and inexpensively made and assembled. The device comprises very few parts and these are easily and cheaply secured. The toy when assembled is quite strong and durable. The same has been amply demonstrated in actual practice and found to be very successful and efficient.

It will, of course, be understood, that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and. defined in the appended claims.
